Summary: Bacteria respond to complex stimuli fields by either accumulating at a distance from the source or evading repulsive forces, depending on the trade-off between beneficial and hazardous effectors. Surprisingly, bacteria lacking chemosensory sensors are still able to swim toward repellents and even in low pH environments.

Summary: The interaction between fungi and plant roots has a significant impact on agriculture and ecosystems. Fusarium oxysporum, a cosmopolitan plant pathogen, can cause wilting disease in a wide range of crops and can also colonize the roots of other plants as endophytes. This study identified a set of candidate effectors in tomato roots and found that they play a conserved role in various fungi and plants.

Summary: Plant diseases caused by necrotrophic fungal pathogens lead to significant economic losses in global field crop production. Effector proteins play a crucial role in facilitating plant colonization and nutrient acquisition by pathogens. Despite limited understanding, recent bioinformatics advancements have aided in predicting and discovering effector molecules from necrotrophic fungi, shedding light on their functional context. Understanding the mechanisms of necrotrophic effectors is essential for developing genetic interventions to enhance plant resistance against these pathogens.

Summary: Developing control measures for plant-parasitic nematodes (PPNs) is highly important due to the significant crop losses they cause worldwide. The growing awareness of the risks associated with chemical nematicides and their alternatives has led to the need for rational molecular control of nematodes. This control strategy focuses on utilizing genetically based plant resistance and understanding the molecular mechanisms underlying plant-nematode interactions. Advances in molecular techniques such as genome sequencing, RNA interference (RNAi), and gene editing have provided better insights into these interactions. This article highlights the tools and resources derived from these interactions, while also addressing the challenges in their use. The need to enhance knowledge about the mechanisms involved in host-specific susceptibility/resistance mediated by PPN effectors, resistance genes, or quantitative trait loci is stressed to improve their effective and sustainable use in economically important plant species. Therefore, it is suggested to employ these techniques on a case-by-case basis to track and optimize PPN control based on specific variables.

Summary: The long-term experiment in moist meadow alpine tundra showed that N addition increased overall nematode abundance, decreased diversity, and shifted the composition of all nematode trophic groups to dominance of bacterial-feeding nematodes adapted to N-enriched environments. The effects of codominant plants on nematode communities were limited, with only the nitrogen-sensitive plant Geum rossii showing notable impact.

Summary: Toxoplasma gondii is an obligate intracellular parasite that chronically infects a third of humans. Recent advancements in T. gondii research have revealed a plethora of parasite-secreted proteins that suppress as well as activate immune responses. The parasite has developed various mechanisms to suppress host immune responses and ensure its own survival and transmission.

Summary: This study analyzed the genome of Botryosphaeria dothidea and predicted 320 candidate effector genes, 124 of which were experimentally tested. The results showed that these effector genes could completely inhibit BAX-induced programmed cell death. Additionally, deletion of specific effector genes significantly reduced the virulence of B. dothidea, indicating their important roles in the interaction between the fungus and its hosts.

Summary: Pathogens pose significant threats to plants, and plants have developed NLRs as important components of their immune system. This review summarizes the mechanisms of NLRs in effector recognition, resistosome formation, and defense activation. NLRs in plants are categorized into typical and atypical based on their domains and evolve together with pathogen effectors. NLRs have been successfully engineered to improve plant resistance against pathogens.

Summary: Parasitic nematodes cause chronic disablement in humans worldwide. Current diagnostics for surveillance of filarial diseases have limitations, and improved assays are needed. We studied the glycan antigens of the parasite Brugia malayi and found that they triggered IgG responses. Our findings suggest potential for developing disease-specific diagnostics for filarial disease control.

Summary: Silicon and its compounds have been found to enhance plant resistance against various phytopathogens. The application of silicon has been shown to regulate different defense mechanisms and reduce the severity of nematode infestation. Understanding the role of silicon in plant-nematode interactions is important for effective management of plant-nematode diseases.

Summary: This study investigated the characteristics of M. graminicola in rice fields in southern Vietnam and evaluated the reaction of 20 rice varieties to this soil-borne pathogen. The 'Tetep' variety showed moderate resistance to the nematode, while further research on the interaction between 'Tetep' and nematodes at histological and molecular levels is needed to develop new rice varieties resistant to rice root-knot nematodes.

Summary: By ingesting soil and organic matter, anecic earthworms influence soil ecological processes by depositing casts on soil surface. This study aimed to compare the effect of anecic earthworms on nematode communities in woodland and meadow in northern Vietnam. The results showed that earthworm casts contain significantly more nematodes and enriched trophic groups compared to adjacent top soil, indicating a less favorable environment for plant parasitic nematodes.

Summary: Meloidogyne graminicola, a nematode pest of rice, shows resistance in the Zh11 variety possibly due to two dominant genes. Incompatibility is characterized by rapid accumulation of reactive oxygen species and cell necrosis. Study of key gene expression and hormonal pathways in resistant plants suggests activation of autophagy and involvement of salicylate signaling in resistance response.
